In order to check how the "nftables" binaries work with Neutron, two
new jobs have been added to the periodic queue:
- neutron-tempest-plugin-scenario-linuxbridge-nftables
- neutron-tempest-plugin-scenario-openvswitch-iptables_hybrid-nftables
In those two jobs, the binaries for "iptables", "ip6tables",
"arptables" and "ebtables" are replaced with the "nftables"
counterparts; by default, newer operating systems use the "nftables"
versions, providing the legacy API to the user but executing the
new packet handling in Netfilter.
